The TE Connectivity 1SNA166777R0000, also identified as M20-I-C5A, is a specialised 20-circuit ESSAILEC multicircuit socket designed for electrical measurement, testing, protection and control applications. Part of the established TE Connectivity / Entrelec ESSAILEC range, it provides a compact and dependable interface for connecting multiple measurement or control circuits within industrial electrical systems.
The M20-I-C5A uses a reverse-mounting configuration and is designed to work with compatible ESSAILEC multicircuit plugs. The modular ESSAILEC architecture enables multiple circuits to be connected and disconnected through a dedicated plug-and-socket interface, helping simplify testing, commissioning, maintenance and equipment replacement.
Designed for demanding electrical installations, the ESSAILEC multicircuit platform has a rated current of 8 A and a short-circuit withstand capability ranging from 25 A for 5 s to 800 A for 25 ms. The grey M20-I-C5A socket weighs approximately 190 g and is supplied with the accessories required for its mounting arrangement together with two coding pins.
ESSAILEC multicircuit connectors provide a dedicated interface for grouping multiple electrical circuits into a single modular connection system. This arrangement can simplify commissioning, measurement, maintenance and equipment replacement by allowing compatible circuits to be connected through a purpose-designed plug-and-socket assembly.
The M20-I-C5A is specifically configured as a reverse-mounted 20-circuit socket and pairs with the compatible FIM20-I plug. Its combination of multicircuit connectivity, coding capability and industrial electrical ratings makes it suitable for protection panels, metering equipment, switchgear and other applications where reliable multi-pole test and control connections are required.
